Fulcrum Rapid Red 3 Disc Brake 2-Way Fit Clincher Wheels - Options

RDB™ RIM DYNAMIC BALANCE

The concept is simple and elegant: balance the weight of the gasket, with an item of similar weight placed on the exact opposite side.

2:1 TWO-TO-ONE SPOKE RATIO™ - DISC BRAKE

A system that is as simple as it is effective, the result of the ingenuity of Fulcrum® engineers and attentive observation of the results of the tests performed on the wheels on a daily basis.

These tests made it possible to understand that the forces that act on the sides of the wheels, and therefore on the spokes, are extremely different; but what’s more, the differences between the front and rear wheels are also evident and significant. The front wheel, in fact, has to remain stable even during braking of the disk on the left side, and the rear wheel, in addition to the sprocket set, has to compensate for the traction of the force on the chain side.

F.I.C. FULCRUM IDENTIFICATION CARD - 100% HANDMADE QUALITY

 Right from its inception Fulcrum® has been marked by feature that continues to this day: that is to design, prototype and industrialise all the wheels characterised by the red “F”.
Indeed these take shape inside of the R&D, the leading-edge department that represents the beating heart of the Italian company.
Every single component of the wheel, the materials chosen and the technologies applied are the tangible result of the effort that Fulcrum® makes every day to give you maximum performance and reliability.

TRACEABILITY

A guarantee of quality

The keyword for our products is: traceable.

If you find a little label attached to any Fulcrum® product, do not remove it. It will provide you a guarantee in case of an ascertained defectiveness of a production batch, and so the component needed or wheel will be traceable.

All this because, devoted to its mission, Fulcrum® demands the absolute perfection and safety for its customers.

WIDE RIM TECH

Fulcrum®’s R&D department, following requests from the competition circuit, has worked to create rims that are wider than before, about 4 mm or more than previously. This technical choice provides an ideal basis for 25/28mm tyres, the sizes currently popular.
This ensures stability, excellent handling and superior comfort.

HIGH STRENGTH ALUMINUM

Special aluminium - the best aluminium wheels require carefully chosen materials. For "High strength Aluminum", Fulcrum® R&D uses only the best aluminium alloy 6082, with artificial ageing T6 temper that stabilises the alloy and gives it maximum life and reliability.
Aluminium 6082 has the highest strength of the 6000 series and has replaced 6061 in many applications. It is generally used for high-stress applications.

MONOBLOCK HUB FOR DISC

The rear hub of a top-quality disc brake wheel is a technical problem to be solved. Fulcrum®’s R&D department found itself facing a fundamental choice: on which side to put the oversize flange of the Two-to-one™ system? Disc or sprocket side? Without question - must stay on the sprocket side.
To combat the loss of braking power from flex and torque of the connector between the two sides of the hub, a special one-piece system has been devised with internal stiffening ribs.

SPECIFIC NIPPLE HOUSING

7% more reliable.

Such a small part, yet so important. The nipples and their housing are one of the most important element that are taken into account during the design of a wheel.

During the development of the new E-Mtb Fulcrum rims, a lot of work was put into this aspect. The housing has been re-designed and now it makes it possible to eliminate completely the nipples' hard work.

Thanks to a special housing, with side guides on both sides, the nipple sets on a stable base, perfectly in position, oriented towards the spoke.

This makes it possible to make the distribution of the tensions in the rim more even, creating thus perceptible benefits in terms of effort and rigidity: this prevents misalignments under stress and, as a consequence, deformation to the structure.
